AUXILIARY AIR-INLET DEVICE FOR INTERNAL-COMBUSTION ENGINES.

To all'whom it may concern:

Be it known that I, PAUL J. eena, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in an Auxiliary Air-Inlet Device for Internal-Combustion Engines, of which the following is a specification. I

This invention relates to attachments for gasoline motors and the primary object is to provide a device for supplying hot air to the explosive charge as it is emitted from the carbureter so that the mixture will be taken into the cylinders at a higher temperatuiie than would otherwise be the case.

One-object of the invention is to provide an attachment of this character that will utilize the 'heat generated by the exhaust and passing through the exhaust manifold of the motor, to mix with the explosive charge as it is ejected from the carbureter, so that-the charge when it enters the cylinder will have a higher coeflicient of combustibility. The invention also aims at the provision of an attachment of this character that may be readily interposed between the carbureter and themanifold of the on dinary gasoline motor and which will be provided with means whereby the exhaust gases from the manifold may be utilized, the same being strained and filtered before they pass into the intake manifold.

In the drawings,

Figure 1 is a side elevation of a gasoline motor showing my attachment applied thereto.

Figure 2 is a fragmentary section through the attachment showing the connecting portions of the intake manifold and the. carbureter. i

Figure 3 is a section taken on the linel3-3 of Figure 2 and Figure 4. is a section taken on the line 4-4 of Figure 1.

By referring to the drawings, its will be seen that the motonA is provided with the usual intahemanifold B and the exhaust manifold C the latter being provided with the discharge pipe which leads to the inuilier, not shown, beneath the ear.

Applicatioh filed December 20, 1917, Serial No. 208,144. Renewed April 27, 1922. Serial No. 557,032.

E is disposed in its usual position beneath the manifold D and the discharge outlet of the carbureter is provided with a flange which ordinarily connects with the flange on the end of the manifold D. In the present instance however, I have interposed a block 1 which is of the same shape as the flanges of the ends of the manifold and carbureter, the block having a central opening for establishing communication between the mani fold and the discharge end of the carburetor. Withinthis opening in the spacing block I have provided a filter constructed of suitable .ioraminous material and including the cylindrical portion 2 which has a conical extension 3 projecting into thcdischarge neck of the 'carbureter as shown to advantage in Figure 1 of the drawing. The spacing block 1 of the flanges on the manifold and carburetorare all bolted tightly together through the medium of fastening bolts 4- extending through the flanges and through the spacing blocks. In one side of the block 1 I have provided a screw threaded opening 5 which communicates with the interior of the block and receives a screw threaded nipple 6 connected to a valve 7 having a hand lever 8 by which. the valve may be opened and closed. A flexible pipe or hose 9 is-connected to the valve 7 through the medium ofa coupling 10 and the opposite end of the hose 9 is adapted to receive gases from the discharge pipe D of the manifold I C. Surrounding the break which is provided in the discharge pipe D is a sleeve '11 forming a chamber 12. This sleeve as shown to advantage in Figure a is connected to the discharge pipe by clips 13 which extend around the pipe and are looped through" openings in the marginal edge of the sleeve 11'. The end of the hose is extended through the sleeve and terminates within the chamber'12 so that the hot gases from the manifold are passed through the pipe and through the valve 7 into the interior of the opening in the hloeir. 1.

In the nipple 5 I have extended one end of a cylindrical strainer 14 which projects transvex-seiy across the opening in the block,

the cylindrical pertion 2 of the filt r having me w an opening through which the strainer 14 projects.

Having thus described my invention, What I claimes new is:

An attachment of the character described comprising a block having a central opening there in, a filter arranged within the
